NEW HARD CAPSULES COMPRISING PULLULAN

摘要

Publicly available pullulan hard capsule shells present certain drawbacks, notably a non fully satisfactory shell mechanical strength (i.e. shell brittleness) at shell low LOD. Improving this property is a particularly desirable goal for pullulan hard capsule shells. The present invention solves this and other objects by providing new hard pullulan capsule shells and capsules comprising (I) moisture, (II) a mono-, di-, and oligosaccharides free pullulan and (III) a setting system. Also provided are an aqueous composition and a dip-molding manufacturing method for the manufacture of such shells and capsules.
